Upon reading some British scientist’s prediction of two species of humans thousands of years hence — a genetically solidified separation of the haves and have-nots — commenters have seemed to overlook the possibility that the haves are rapidly divesting themselves of the only thing that is actually worth having as they rend themselves from the sometimes inconvenient and often painful embrace of nature. As a cultural matter, it perhaps comes down to aesthetic preference, but such marches in the presumed direction of evolution must incsusceptibility to unforeseen pitfalls. Consider:

These humans will be between 6ft and 7ft tall and they will live up to 120 years.
“Physical features will be driven by indicators of health, youth and fertility that men and women have evolved to look for in potential mates,” says the report, which suggests that advances in cosmetic surgery and other body modifying techniques will effectively homogenise our appearance.
Men will have symmetrical facial features, deeper voices and bigger penises, according to Curry in a report commissioned for men’s satellite TV channel Bravo.
Women will all have glossy hair, smooth hairless skin, large eyes and pert breasts, according to Curry.
Racial differences will be a thing of the past as interbreeding produces a single coffee-coloured skin tone.

What if our clear and visible distinctions have been a key ingredient of our species’ success? On an individual level, it allows us to recognize each other — to identify (if we’re to be reductive) others whom we know to possess particular information. On a regional level, it has improved our odds at predicting others’ beliefs, associations, and previous experiences.
Me, I’ll throw my lot in with those who revel in the grubby difficulties of organic life. Cultural evolution requires improvement of our handling of nature and its differences, not our self-extrication from them.
